[OpenAFS] AFS and firewalls, in general terms

[Mike W Ellwood]

Sorry, I am sure this is something of a faq, but some of what I
thought to be the case may not actually be the case, so perhaps
perhaps someone can kindly refresh my memory/inform me/clear up 
some confusion:-

If I want to run a server running all the standard server
daemons from behind a firewall, what protocols do I need to be allowing
through, assuming that I want all normal AFS functions to be transparent
to the outside world,
but nothing else (or nothing much else)?

Thank you.
